STEP 2
Data Collection
Prepare dish alignment, verify amplifier and filter wiring, and run baseline recordings.
Record with consistent gain settings and save metadata for each observation.
STEP 3
Processing
Run the processing pipeline to convert raw SDR captures into analyzable spectra.
Compare output against reference frequency ranges around the 21 cm line.
STEP 4
Validation
Repeat observations where possible and compare trends over multiple sessions.
Log anomalies so your team can refine hardware configuration and calibration.
